Release/v2.0.0 - pre-compiled-builds

[reed-jones]

This release contains a fairly major overhaul of the build system.
It exposes the 'index' of the item to the consumer through the slot props.

The main braking change is how styles are imported.
It removes & exposes the included stylesheet as a separate install. Initial installation has changed from:

import VueTable from '@pderas/vue2-table'; // styles are included by default
Vue.use(VueTable)

to

import VueTable from '@pderas/vue2-table'; // styles must be included manually if desired
import '@pderas/vue2-table/dist/vue-table.css';
Vue.use(VueTable)
